Web8 apr. 2024 · The lithosphere is the outermost layer of Earth, composed of the crust and the brittle part of the upper mantle. The term lithosphere is derived from the Greek words "lithos," meaning stone,... WebThe lithosphere is made up of the crust and the uppermost part of the mantle. 2.2 Mantle: It is the layer between the core and crust. Its upper portion is called the asthenosphere. Asthenosphere is the main source of magma over which continental plates move. The density of this layer varies from 3.3 to 5.7 g/cm 3.
WebThe lithosphere is composed of solid materials and encompasses the continental crust. It is also formed by the oceanic crust and tectonic plates that move slowly and which are as large as a continent. It is composed … WebMuch of the continental lithosphere is felsic (i.e. granitic), and normally more buoyant than the underlying mafic/ultramafic mantle. When mafic magma rises through thick continental crust, it does so slowly, more slowly than when magma rises through oceanic plates. This gives the magma lots of time to react with the surrounding country rock.

One factor determining an igneous rock's composition is its classification as either a felsic or mafic rock. Felsic rocks are dominated by silicon and aluminum minerals, whereas mafic rocks are dominated by magnesium and iron minerals.
WebIt has a mass of 4.01 × 10 24 kg and thus makes up 67% of the mass of Earth. [1] It has a thickness of 2,900 kilometers (1,800 mi) [1] making up about 84% of Earth's volume. It is predominantly solid but, on geologic time scales, it behaves as a viscous fluid, sometimes described as having the consistency of caramel.
